Unfold hank of yarn.
Cut a length of yarn twice the height of the pot. The yarn is constructed as a tube. Gently slide your arm through the yarn tube, grasp the yarn, then pull yarn tube back up your arm to double it. This doubled piece will be the pouch for the flower pot. With needle and thread, gather cut edges of pouch and draw tightly together to close and secure with stitches.
Cut a length of yarn about 26 in. (66 cm) long. Whip stitch piece to top of pouch. Sew ends of this top piece together. Cut a length of yarn equal to the circumference of top of pot and set aside.
Cut remaining yarn into thirds for hangers. Sew one end of each hanger to top of pouch, spacing them evenly around top edge of pouch. Gather top edge trim behind each hanger and stitch in place to reinforce hangers. Knot ends of hangers together.
Wrap remaining piece of yarn around pouch below top edge trim and stitch in place at hangers.
